#Markus Lauer's message:
"""
does XPath work with html Documents? In the below code in the result of
the XPath evaluation the <H1>...</H1> node is missing.
Do I use XPath in a wrong way? Is it a bug? Is XPath not supposed
to work with HTML files?
I tried this with 4Dom-0.9.2, XPath-0.8.2 and 4Suite-base-0.7.1
Python 1.5.2 under SuSE Linux 6.3
(by the way: the hole 4Suite compiled without any problems out of the box)
